内容記述 |
Three Antarctic iron meteorites, Yamato-790724,ALH-77263 and ALH-77289 have been studied from the viewpoint of analytical chemistry. Fourteen elements, Ni, Co, P, As, Au, Cr, Ga, Ge, Ir, Pt, Re, Ru, Sb and W were determined. From the results, Yamato-790724 was classified into Group IIIA. ALH-77236 and ALH-77289 were classified into Group I. The elemental distributions of Ni, Co, P and S in the three meteorites were examined. Phosphide, (Fe, Ni)_3P and sulphides, FeS and FeCr_2S_4,were detected. Morphology of the compounds was observed and the distribution of them was measured. Some discussions are given to the facet pits formed by the etching method and the orientations. Twinned structures found in ALH-77289 are considered to have been caused by strong mechanical shock. |
